This invention relatesto a' faucet constitutingV theoutlet ofa; tank orreservoir con taining the' Abeverage decoction lrnoWrn Vas coffee. Thisdeco'ction contains!insolut-ion an element, probably caffeine,Which'forms ar` viscous coating on'the'wall of the ductof'a faucetused't'o dispense thebeverage, the latter oftenV remaining at rest inthe faucet be; tween periods of use thereof. This coating, if allowed toremain indefinitely, affects the taste of the beverage. Y Itis thereforevery desirable that the coating be removed fre faucet from thereservoir, and quickly closed f toV condition the faucet for use.

Figure 6 is a fragmentary section'sim'ilar to a 'portion of Figure 15,"showing'y alternative means foi` interengagingthe rock-shaft' and valvestem hereinafter described.

Figure 7 is al fragmentary perspective View, showing the housing portionof Vthe' faucet in cross section, and alternative 'ineansy for separablyconnecting the housing with The same reference characters indicate thesame parts in all of the figures.

The casing of my improved faucet comprises a spout portion 12, adaptedto be connected Wit-h a coee reservoir 14, and including a dischargenozzle 15, and a valve seat 16, and aL housing portion 17, havingV avalve 18, adapted to closeon the seat 16, and means` for' opening and'closingl the valve. The spout vand housing are preferablylconnlectedtbyfY ahinge Which permits the separationfofi the housingfrom the spout, by afswingmgmovement. ofv the housing, shown byv Figure- 5. They hinge is located atlone'side off the faucet andpreferably include'sV an ear* 19 projecting laterally from the innersection, an ear 20 projecting longitudinallyfrom the housing and offsettherefrom, andr a .p'intl'e' 21 connecting the ears.` The spoutL andhousing are provided withcoinplenfientalfI couplingy members, onecarried by the spout, and the other by the housing, said members beingadapted to cooperate With the hinge i'n operatively connectingthe.sections,'as shown by Figure 4,`

and separable from each other to permit? thev Separationrof the/housingfrom the spout, andtheefXposure ofthe bore of the'spout and thejvalveSeat 16, as'shovvnvr by Figure 5.

"Ihe coupling members preferably com-- prise a'hasp''a, pivoted at 23 toanear 24, projecting laterally from the side of the housing, oppositethe hinge ear 20, the hasp being'providedwith a slot 25, and an ear 26,projectingfrom tlielside of the spout opposite the hinge ear 19, andarranged to enter the slot 25 when the hasp is swung to the position'shown' byv Figure 3, the-closed end 25""A (Figure 5) ofv the slotVbearingv on onel edge'of the ear 276, so that theinner end of the*housing` is clamped against the outer end' of the spout. l To'insure aliquid-tight `ioin't between the spout and'housing, I provide the spoutwith` an annular end face,preferably formed by a compressibleannular'washer 28, partly inserted in` a' groove formed in the outer endofthe spout, the housing being provided with anjanjnular end face 29,complemental to andadapted to bear on said'washer.

Awhich vis longitudinally movable in the outer section andv*constitutesy an element of the valve-opening and closing means'.r Thehous-A ingiis providedfwith aflexible diaphragm 31,

. r Thev valve'lfv .is-provided with a stem 30,'

preferably includes, in addition to the valve stem, a. spring 32,interposed between an adjustable abutment V33 in the housing 17 and thevalve stem, and adapted to close the valve on the seat-16, andarock-shaft 34, journaled in bearingsY 35 and 36 (Figure 2) in thehousing and provided with an operating handle 37. -he rock-shaft and thevalvestem are interengaged by suitable connections so that rotationofthe rock-shaft in one direction opens the valve against the closingpressure of the spring 32.

The interengaging connections shown by Figures 2, l and 5, include gearteeth 3S on the rock-shaft, and gear teeth 39 on the valve-stem. Thealternative interengaging connections shown by Figure 6, include afinger on the rock-shaft, and a shoulder 46 on the valve-stem on whichthe linger bears, the shoulder being one end of a recess formed in thevalve-stein.

The spout and housing may be separably connected by means other` thanthe hinge and coupling members, shown by Figures l, 2, 3, and 5, analternative connecting means being shown by Figure 7. In this ligure theinner section is provided with tappedears 47, with which are engagedheaded screws 48. The housing is provided with ears 49, having openslots 50. Vhen the spout and housing, which are shown separated byFigure 7are abutted together, the screws enter the slots and may beturned, to cause their heads to eXert pressure on the ears 49, and thuspress the meeting ends closely together and form a liquid-tight joint.

The turning movements of the rock-shaft may be limited by stop pins Ll0and 4l (F igure 3) fixed to the rock-shaft, and a pin 42, fixed to thehousing.

The valve-stem is guided in its movements by guides 43, in the housing17. The spring 32 exerts sufficient pressure on the valve stem, inclosing the valve, to turn the rock-shaft after the handle 37 isreleased by the operator.

rIhe spring automatically projects the valve from the housing when thelatter is displaced, as shown by Figure 5, so that the valve isautomatically seated yieldingly on the valve seat 1G, when the housingismoved to its operative position.

`When the sections are separated, as shown by Figure, and the hasp 22 isswungbackward, as shown by dotted lines, aA brush or swab may beinserted in the bore of the inletportion l2, to remove therefrom acoating deposited thereon. v v

I am not limited to the embodiments of the invention shown by thedrawings, except discharge nozzle communicating with the recess, betweenthe end yface and the valve seat, the bore of the spout beingunobstructed and arranged to becleaned by a swab insertedV through therecess and the valve seat, a housing having internal guides and acomplemental end face, means separably confining the housing in anoperative position'with its end face bearing on that of the spout, the

housing being displaceable to an inopera-V tive position, a valve havinga stem movable in said guides, a spring acting on thel valve stem toyieldingly project the valve from the housing, so that the valve isautomatically seated on the valve seat of the spout by movement of thehousing, to its operative position, a rock-shaft journaled in thehousing and provided with an operating handle,

and connections between the rock-shaft and valve stem, whereby when theshaft is r0- tated in one direction, the valve is opened against theclosing pressure of the spring, the arrangement being such, that whenthe housing is displaced from its operative position, access of' a swabto the bore of the spout is permitted.

2. An internally cleanable faucet, comprising a spout adapted forattachment to a reservoir and provided with an annular outer end face, arecess surrounded by said face, a valve seat within the recess, and adischarge nozzle between the end face and the valve seat, the spoutbeing cleanable by a swab inserted through the recess and valve seat, anindependently movable housing separably connected with the spout andhaving a complemental annular inner endV face and internal valve-guidingmeans, a valve guided by the housing, valve-operating means carried bythe housing, and means separably clamping the end face of the housingagainst the end vface of the spout, to render the faucet operative andinoperative, the arrangement being such that when the faucet isoperative, the valve is maintained in position to openand closethevvalve seat, and when the faucet is inoperative, access of a swab tothe faucet bore is permitted.

In testimony whereof I have aHiXedmy signature., l
